Thank you for completing this exercise. Now
you may select Module IV from Course contents.
22
Your answer is not correct. The correct
answer is 80 mm rainfall received in 30
minutes indicate high intensity of rainfall.
Continue
23
You are right. 80 mm rainfall received in 30
minutes indicate high intensity of rainfall.
Continue
24
Your are right. Soil erosion may result with a
high intensity rainfall like 120 mm of rainfall
in 1 hour.
Continue
25
Your answer is not correct. The correct answer
is Soil erosion may result with a high
intensity rainfall like 120 mm of rainfall in 1
hour.
Continue
26
You are right. Soaking rain like 25 mm of
rainfall a day before will be useful to take up
the sowings.
Continue
27
No please. The correct answer is Water from
high intensity rainfall mostly result in run off
with very little water saturating the soil
profile. So soaking rain like 25 mm of rainfall
a day before will be useful to take up the
sowings.
Continue
28
No please. You are partly correct because the
amount of rainfall received is not clear from the
statement to take up the sowings. The correct
answer is Soaking rain like 25 mm of rainfall a
day before will be useful to take up the sowings.
Continue
29
You are right Rains received during June to
September, and October to December are monsoon
rains.
Continue
30
No please. Rain during March to April are not
monsoon rains. These rains are known as summer
showers The correct answer is Rains received
during June to September, and October to December
are monsoon rains.
Continue
31
If you are not sure, the answer is Rains
received during June to September, and October to
December are monsoon rains.
Continue
32
You are right This break in rainfall coincides
with pod development in groundnut and thus affect
the pod formation and development.
Continue
33
No please. Please note the break in rainfall.
Rains were received during flowering and
harvesting stages and so, these stages may not be
adversely affected due to moisture
availability. The correct answer is Breaks in
rainfall during late August and early September
coincides with pod development in groundnut, and
thus affect the pod formation and development.
Continue
34
You are right Higher temperatures over land than
sea results in differential heating between land
and sea. Consequent to this, air pressure will be
higher on land compared to the sea. This pressure
gradient brings moisture-laden winds towards land
resulting in monsoon rains.
Continue
35
No please. The correct answer is Higher
temperatures over land than sea results in
differential heating between land and sea.
Consequent to this, air pressure will be higher
on land compared to the sea. This pressure
gradient brings moisture-laden winds towards land
resulting in monsoon rains.
Continue
36
You are right Near water body the air will be
saturated with moisture. So, the RH will be quiet
high (gt60) during summer in the coastal areas.
Continue
37
No please. The correct answer is Near water
body the air will be saturated with moisture. So,
the RH will be quiet high (gt60) during summer in
the coastal areas.
Continue
38
You are right Relative humidity is measured
using hygrometer (Fig.)
Continue

No please. Barometer is used to measure air
pressure (top Fig.). The correct answer
is Relative humidity is measured using
hygrometer (bottom Fig.)
Continue
40
No please. Anemometer is used to measure wind

is Relative humidity is measured using
hygrometer (bottom Fig.)
Continue
41
If you are not sure, here is the
answer Relative humidity is measured using
hygrometer (Fig.)
Continue
42
You are right You will feel comfortable if RH is
low. At high RH you will sweat more, feel sticky
and uncomfortable.
Continue
43
No please. The correct answer is At high RH
you will sweat more, feel sticky and
uncomfortable. You will feel comfortable if RH is
low.
Continue
44
You are right Sunshine is recorded to calculate
day length.
Continue
45
No please. Sunshine do not provide maximum and
minimum temperatures. The correct answer
is Sunshine is recorded to calculate day length.
Continue
46
If you are not sure, here is the
answer Sunshine is recorded to calculate day
length.
Continue
47
You are right Mercury thermometer is used to
measure maximum temperature.
Continue
48
No please. Alcohol thermometer is used to
measure the minimum temperature. The correct
answer is Mercury thermometer is used to
measure maximum temperature.
Continue
49
No please. Wet and dry bulb thermometer is used
to measure the relative humidity. The correct
answer is Mercury thermometer is used to
measure maximum temperature.
Continue
50
If you are not sure, here is the answer Mercury
thermometer is used to measure maximum
temperature.
Continue
51
You are right There will not be any short-wave
radiation during the nights due to the absence of
sun. This results in lower temperatures during
nights compared to the day temperatures.
Continue
52
No please. The correct answer is There will
not be any short-wave radiation during the nights
due to the absence of sun. This results in lower
temperatures during nights compared to the day
temperatures.
Continue
53
If you are not sure, here is the answer There
will not be any short-wave radiation during the
nights due to the absence of sun. This results in
lower temperatures during nights compared to the
day temperatures.

54
You are right Air-pressure is measured using
aneroid barometer (Fig.)
Continue
55
No please. Hygrometer (top Fig.) is used to
measure relative humidity. The correct answer
is Air-pressure is measured using aneroid
barometer (bottom Fig.).
Continue
56
No please. Anemometer is used to measure wind
velocity (top Fig.). The correct answer
is Air-pressure is measured using aneroid
barometer (bottom Fig.).
Continue
57
If you are not sure, here is the
answer Air-pressure is measured using aneroid
barometer (Fig.).
Continue
58
You are right The air pressure will be lower
with less air. That is why you feel difficult to
breath as you climb a hill or more floors in a
high-raised building. More the air, higher will
be the pressure.
Continue
59
No please. More the air, higher will be the
pressure. The correct answer is The air
pressure will be lower with less air. That is why
you feel difficult to breath as you climb a hill
or more floors in a high-raised building.
Continue
60
If you are not sure, here is the answer The air
pressure will be lower with less air. That is why
you feel difficult to breath as you climb a hill
or more floors in a high-raised building. More
the air, higher will be the pressure.
Continue
61
You are right A low-pressure system indicates
cyclonic winds and subsequent possibility of
rain.
Continue
62
No please. A high-pressure system leads to
cooler temperatures and clear skies. The correct
answer is A low-pressure system indicates
cyclonic winds and subsequent possibility of rain.
Continue
63
If you are not sure, here is the answer A
low-pressure system indicates cyclonic winds and
subsequent possibility of rain. A high-pressure
system leads to cooler temperatures and clear
skies.
Continue
64
You are right Anemometer is used to measure wind
(Fig.).
Continue
65
No please. Air-pressure is measured using
aneroid barometer (top Fig.). The correct answer
is Anemometer is used to measure wind (bottom
Fig.).
Continue
66
No please. Hygrometer (top Fig.) is used to
measure relative humidity. The correct answer
is Anemometer is used to measure wind (Fig.).
Continue
67
If you are not sure, here is the
answer Anemometer is used to measure wind (top
Fig.). Air-pressure is measured using aneroid
barometer (middle Fig.). Hygrometer (bottom
Fig.) is used to measure relative humidity.
Continue
68
You are right Winds move from a high-pressure
system towards a low-pressure system.
Continue
69
No please. The direction of winds between sea
and land depends on the air pressure differences.
If air pressure is higher over the land, then the
winds move towards the sea and vice-versa. The
correct answer is Winds move from a
high-pressure system towards a low-pressure
system.

You are right The clouds in the picture are
fair-weather clouds.
Continue
71
